Printed concrete as a versatile material for interior decoration, facades and landscaping

Concrete - one of the most popular and versatile building materials, can not do without either large organizations or private owners. Although the main purpose of the concrete - be the basis for further finishing, it is in itself can become a decoration of the interior, the facade or the plot. For example, using a printed concrete can transform walls, floors, plinths, steps, fences, walkways and recreational areas.

Concrete Canvas - the "draw"

Taking the typical cement-sand mixture, you can get almost any texture using as special tools and means at hand. Printed concrete stamped otherwise called, because more often than drawing on the surface it is applied to the stamp. The best in terms of quality of the simulation, and in terms of the durability of polyurethane seals are considered, but they are also the most expensive. Plastic stamps are available, but they are easily damaged, and provide simple relief. Special rollers are also used, with their help, usually applied longitudinal figures. As for the available tools, there's someone on that imagination will suffice - prints can be done in any terrain.

The nuances of a solution

The proportions of the standard solution - in the cement of the three parts of sand, but the addition of a plasticizer to make a universal weight elastic, and it will be easier to work with. In addition, cured concrete and characteristics will be higher than the analog without the additive. Since mimic usually colored materials are used in the preparation of the mixture, and pigments. Fortunately, today in DIY stores a large variety of dyes in all colors of the rainbow as a concentrated solution or dry powder.

The proportions depend on the selected brand and desired shade, but do not pour more than recommended by the manufacturer, this may deteriorate the characteristics of concrete. But this method is designed for small volumes and surfaces are not subject to wear, and is most commonly used in landscape design to decorate small forms or in the interior.

Application technology printed concrete on tracks

If you talk about the garden paths, stairs or recreation areas, and different printing technology for concrete and raw materials base. To prepare the solution used Portland cement is at least 400-M, the plasticizer is not recommended, as required. Also sand, gravel to make kneading (fraction 5-20 mm) and a polypropylene fiber. To improve the wear resistance of the printed surface, use a color hardener, a separator and nail. The whole process is as follows:

  • Manually or mechanically prepared solution.
  • Spread on a prepared surface (the preparation method depends on the zone), compacted, smooth down.
  • Once the mixture starts to set, it is recommended to roll the roller to the coarse fractions settled.
  • Scatter on the concrete surface first portion hardener smooth down (5-10 minutes), dub edges and corners.
  • Uniformly distribute the second part of pigment, smooth down.
  • Apply separator (liquid or powder), it is not only additionally stain concrete, but also prevents sticking stamps. Some go without separator, lubricating dies mining.
  • Stamping begin when the concrete becomes a "plasticine" and when pressed with your finger turns hole depth of a few millimeters.
  • Dies is applied to the surface in the order of priority or posegmentarno, jam its own weight or light rammer.
  • After one day, adjusted drawing - smooth out irregularities cut deformation (shrinkage) sutures.
  • After a further day the concrete is washed with water from a hose, the surface is treated with an acid (hydrochloric).
  • The final stage cover drawing protective and decorative paint.

Damage pattern continues in this manner as long as possible have been used hardeners and coating, and the abrasion process is stopped. Well, you can simulate anything you want - from decking and Mexican stone to leather and wood bark.

Recommended composition of the concrete cube, type M-300.

1) Cement - 450-500 kg. (Portland cement 400 M);

2) Crushed - 1,000 kg. (Fraction 5 \ 20 mm);

3) Sand - 500 kg. (Depending on time of year and the properties of the sand, the amount of sand can be increased, and reduce dropouts);

4) Screenings - 200 kg.

5) Water - 200-220 liters.

6) Fiberglass - 600 c. (Added directly to the mixer / mixer, 15 min. enough for a full mixing.

In hot weather, you can order the concrete under the pump, it will retain elasticity longer, which will increase the time it is processed. If you do not have the possibility to order concrete of this proportion, order M-300, zapesochenny under the pump, without the addition of chemicals. No intrusion of concrete mixture containing the salt and air entraining additives promoting vysoloobrazovaniyu. The concrete mix should not contain inclusions of clay. The recommended grade of concrete - not less V22,5 (grade 300).
